To evaluate the clinical effect of surgical resection and local advancement flap repair of the postoperative chronic refractory incision.

From February 2016 to January 2021, 42 patients with postoperative chronic refractory incision were selected from the Department of Plastic and Aesthetic Surgery, Beijing Shijitan Hospital, Capital Medical University. After improved the preoperative examination, the patients were scheduled to undergo surgical repair. The incision line was designed at 0.5 to 1.0 cm around the refractory incision. The incision and the lesion of the base were completely removed, down to the deep fascia or sarcolemma under local or general anesthesia, and the defect was repaired by local advancement flap. The blood supply of the flap and the incision healing time and condition of wound healing were observed. Pathological examination was performed to observe the inflammatory reaction and inflammatory cell infiltration of the incision and peripheral tissue of the incision.

The blood supply of the local flap was normal after operation, and there were no signs of infection such as redness, swelling and pain. All patients healed in Ⅰ stage. The incision healing time was (12.0±3.0) days. Pathological examination showed that the inflammation in the center of the incision was serious, lymphocyte infiltration (140 ± 21) cells /HPF, and the structure of the cutting edge was normal. Following up for 2- 6 months, there was no recurrence of the wound.

The refractory incision and the inflammatory lesion at 0.5-1.0 cm around the incision are completely removed, and the wound surface can be repaired in Ⅰ stage with local advancement flap. There is no recurrence after follow-up, and the operation effect is satisfactory. It is worthy of clinical application and promotion.
